On this page it says the recommended dosage is 600 IU https://ods.od.nih.gov/factsheets/VitaminD-HealthProfessional/ https://ods.od.nih.gov/factsheets/VitaminD-HealthProfessiona... Are there any other opinions?

Yes. 2000 IU and 5000 IU daily are common recommendations from medical groups in the USA.

  I take 5000iu daily. My levels are fine. They were low before I started taking vitamin d.

My doc has had me taking 15,000 IU for four years or so. So, some other opinions.

  Your doctor also had you coming back for blood work yes? High doses are meant to top up your liver. Once that works your serum levels will climb and you would cut back.

    He started lower, but 15K is where blood levels were normal, and they've remained steady since. Soon we'll see if 6 months of staying inside has affected things. :)

  How frequently?

    Daily. Started at 5000, then 10, then 15, which is where blood work was okay.

I live in Seattle and taking 2000 UI daily barely got me to “sligtly deficient”. Now I upgraded to 4000 UI daily hoping to get to the lower part of the normal range. I talked to the doctor and she told me that among blood tests she ordered most people have slightly/moderately deficient levels, very few low normal, and over the years only one person tested high normal (i.e. when taking supplement would be detrimental). Moral of the story - do a blood test, but if you live in high-ish lattitudes, most likely you have vitamin D deficiency.

  and especially if you live where people don't tan, they rust. Mind you, Seattle is the only city I've ever really liked, and I wish I could live there now.

Your blood levels tell how much vitamin d your body is holding onto. In addition to not getting enough sun you could have an absorption problem, in which case they may try other things but one of those is just cranking the dose.

You should test your serum D3 level first, if its fine, why take anything? If its low, take whatever gets you into the normal range. Personally, I think 600 IU isn't going to move the needle much, based on information here https://www.grassrootshealth.net/project/dcalculator/?_ga=2.144159868.853691391.1602309491-1147360412.1602309491 https://www.grassrootshealth.net/project/dcalculator/?_ga=2....
